Pittosporum macrophyllum Laut. & K. Sen. (Plttospora- 
ceae.) 39728. Seeds from Nice, France. Presented by Dr. 
A. Robertson-Proschowsky . "The plant has existed in my 
garden for more than 20 years. It is the most beautiful 
of the dozen or so Pittosporum species which I cultivate. 
The leaves occasionally attain nearly the size of those of 
Magnolia grandiflora and the flowers are perhaps not sur- 
passed in fragrance by any other flower. Indeed the fra- 
grence is most "exquisite. Would such highly fragrant 
flowers not be of value for the extraction of perfume?"

Primus pseudo-cerasus Lindl. ( Amygdalaceae . ) 39743-798, 
39820-826. Cuttings of sixty- three varieties of Japanese 
flowering cherries from Tokyo, Japan. Presented by the 
Arnold Arboretum through Its collector, Mr. E. H. Wilson. 
The Arnold Arboretum sent Mr. E. H. Wilson to Japan last 
year for the purpose, among other things, of arranging for 
an authentic named collection of the Japanese Cherry Blos- 
som trees. Mr. Wilson secured botanical specimens of a 
large private collection of these trees and the budwood 
was taken by him personally from the same trees and the 
budwood from each variety was given its own correct Japan- 
ese name by the owner of the collection who is known to be 
an authority on cherry blossom trees. This collection 
will be propagated and sent out under a cooperative agree- 
ment with the Arboretum and under these authentic Japanese 
names made permanent by Mr. Wilson's herbarium specimens. 
Quercus insignis Mart. & Gall. (Fagaceae.) 39723. Acorns 
of a white oak from Zacuapam, Vera Cruz, Mexico. Purchas- 
ed from Dr. C. A. Purpus. "They were sent to me by a 
friend Sr. Guillermo Ziche from Huatusco and were col- 
lected in the Sierras west of town at about 1500-1600 feet 
altitude. I am sure you will be able to grow them in the 
southern part of Florida where the palms {Roystonea regia) 
grow. They need a moist climate, sub-tropical forests do 
well." (Purpus.) "The tree is rapid In growth, and quite 
different in habit from most oaks. It reaches an ultimate 
height of 60 to 80 feet or more, is quite erect, and sends 
out large branches at the height of 30 or 40 feet above the 
ground. It is found in considerable abundance about midway 
down the flanks of Mount Orizaba, being most common about 
Chiapas, according to Dr. C. A. Purpus, who has recently 
been collecting in that region. It is a white oak,- matur- 
ing its fruit the first season; and being a white oak, its
